Applications & Uses

Description

This quinolone alkaloid was first isolated from the roots of Dictamnus albus and subsequently found in Helietta longifoliata. It is very hygroscopic and turns red on exposure to light. Extraction of the roots under extremely mild conditions show the alkaloid to be a true base and not an artifact of isolation.

Uses

Isodictamnine is a phototoxic furoquinoline compound of the Turnipaceae family. Isodictamnine is phototoxic to certain bacteria and yeasts under long-wave UV light[1].
